More than 300 of the world's top Rhythmic gymnasts, including seven 2012 Olympians, will compete for the titles at the 2014 World Rhythmic Gymnastics Championships this month in Izmir (TUR) according to the nominative lists just published on the FIG website.

After incredible results at the 2013 Worlds and 2014 World Cups, all eyes will be on Yana Kudryavtseva (RUS) at the World Rhythmic Gymnastics Championships in Izmir (TUR) this month. Below, her Ribbon performane at the 2013 Worlds.

Fifty-five countries from all continents have inscribed to compete in Izmir. The 323 gymnasts registered include all World champions from 2013, including Yana Kudryavtseva (RUS, All-around, Ribbon and Clubs), Margarita Mamun (RUS, Ball, Clubs) and Ganna Rizatdinova (UKR, Hoop) and reigning World champion Groups from Belarus (All-around), Spain (5 Clubs) and Russia (3 Balls/2 Ribbons).

The 33rd edition of the FIG Rhythmic Worlds is set for September 22-28 in Turkey, a country historically known as the crossroads between East and West. The location mirrors this year's Rhythmic competition, where gymnasts from every continent will be seeking to challenge for medals against Rhythmic elites from Eastern European countries, who have long dominated the sport.

Dethroning the easterners won't be easy. The top name in Rhythmic Gymnastics is currently Kudryavtseva, who at just 15 earned the World All-around title last year in Kiev (UKR). Kudryavtseva, who is well aware of being the latest in a long line of showstopping Russian Rhythmic champions, stands out for her youth and potential. The young Muscovite, daughter of a Soviet Olympic swimmer, has only improved following her win in Kiev -- in 2014 she has won nearly every competition she has entered, and swept the gold medals available at two World Cup events.

At competitions she didn't win, Kudryavtseva was second to her teammate and nearest rival, Margarita Mamun. Before she celebrates her 17th birthday on September 30, Kurdyavtseva may well be a two-time World All-around champion, something no woman has accomplished in the sport.

Mamun, along with teammates Maria Titova and Aleksandra Soldatova, will contend for multiple medals in Izmir, and is perhaps Kurdryavtseva's biggest competitor for the individual All-around title. Though brilliant when she hits, the 18-year-old has not been entirely consistent at big competitions this year, opening the door for others to surpass her. Those include 2013 World bronze medallist Melitina Staniouta (BLR), who won silver at the 2014 European Championships in June, as well as Son Yeon Jae (KOR), who made history for her country by winning the Lisbon World Cup this past spring, and Neta Rivkin (ISR), a 2012 Olympic All-around finalist who finished just off the podium at this year's European Championships.

Others looking to challenge for medals include China's Deng Senyue, who also competed at the Olympic Games in 2012 and finished fourth All-around at the 2013 Worlds, Patricia Bezzoubenko (CAN), a partly Russian-trained gymnast who won four out of five gold medals at last month's Commonwealth Games, and rising stars Jasmine Kerber (USA) and Angelica Kvieczynski (BRA), who each won multiple medals at the recent Pan American Championships in Canada.

Thirty-two countries will compete in Group competition. The top three from the 2013 Worlds are likely to be challenged by former World gold medallists Italy and Bulgaria, both of whom will be looking to recapture titles won in 2011.
